Two slits S and S lie on the x axis and symmetric with respect to y axis are illuminated by a parallel monochromatic light beam of wavelength I as shown The distance between slits is d X Point O is the mid point of the line S S and this point is considered as the origin The slits are in horizontal plane The interference pattern is observed on a horizontal plate acting as screen of mass m which is connected to one end of a vertical massless spring of spring constant k The other end of the spring fixed to ground At t 0 the plate is at a distance D d below the plane of slits and spring is in its natural length The plate is released from rest from its initial position The rate by which fringe width will increase when acceleration of plate is zero is plate S O eeeeeee 41 Hx S k m
